For air transport, in particular, airlines stopped flying altogether and were forced to ground hundreds of planes worldwide involuntarily. Airports had to close their terminals for a long time, wholly suspend operations, and its resumption required significant organizational changes. This article summarizes the measures related to the COVID-19 pandemic adopted by airports to minimize the risk of spreading the disease. The article focuses on countermeasures and their implementation at selected airports in a specific time frame and airports’ behavior during a pandemic which varies depending on country and time of the year. The results demonstrated that steps being taken at airports include the use of face coverings or masks, social distance, enhanced cleaning and disinfection, or temperature checks and/or symptoms (fever, loss of smell, chills, cough, shortness of breath), RT-PCR (reverse transcription-polymerase chain reaction) screening and data collection with health declaration. These measures have now become an essential standard for the operation of airports and can, therefore, be used to assess the level of airport safety achieved.

Introduction and Ilaria Henke Since early cases were identified in Wuhan, China, at the end of December 2019, coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome Received: 29 June 2021 coronavirus 2 (SARS-CoV-2), has been spreading rapidly [1,2]. The outbreak of COVID-19 Accepted: 28 July 2021 Published: 29 July 2021 was declared a pandemic by the World Health Organization (WHO) on March 11 2020, and now it is considered global, with significant autochthonous transmission in different Publisher’s Note: MDPI stays neutral countries [3]. The virus that causes COVID-19 is released, primarily in droplets that can be with regard to jurisdictional claims in propelled a short distance away and in smaller aerosol particles that can stay suspended published maps and institutional affil- and move further. If these particles enter a person’s mouth or nose, either directly or iations. through hands, another person may be infected. In some cases, transmission via surface contact is also probable [4,5]. According to the WHO, it takes 5–6 days after being infected for symptoms to become visible. The common symptoms are fever, cough, tiredness and headache [6].

Tourist mobilities helped COVID-19 become a global pandemic. Due to mobilities being a proper theoretical framing where positions tourism is a part of everyday life, the disease spread so quickly [10]. According to the study by the authors of [11], the relationship between positive COVID-19 cases and transport accessibility of an area was investigated within a multiple linear regression model. The estimation outcomes reveal that transportation accessibility was the variable that better described the number of COVID-19 infections, indicating that the larger the accessibility of a particular geographic area, the easier the virus reaches its population. The COVID-19 pandemic has also impacted air transport mobility internationally and the airline industry in general. Numerous airline travel restrictions have been imposed, potentially leading to significant long-term effects on the global airline industry [12]. Aviation is one of the industries that has been experiencing most problems due to the results of the pandemic outbreak, despite apparently being one of its most significant initial drivers [13]. However, most studies demonstrated that contracting COVID-19 during air travel is lower than from an office, classroom, supermarket, or train. Air travel might appear such as the ideal way for COVID-19 transmission: it carries many people into a limited space, often for hours at a time. However, many modern aircraft have great high-efficiency particulate air (HEPA) filters that catch more than 99 per cent of particles in the air, including microbes as SARS- CoV-2 [14]. However, being in a plane and flying might not even be the most dangerous part of travel. According to studies [15,16] the more hazardous part is staying at the airport. Airports are potentially dangerous places for swapping microbes. They’re closed in, with no open windows and a high concentration of people, especially during peak hours. The crisis has forced the aviation industry (especially airports) to adapt to the situation quickly. With many aircraft grounded due to a substantial decrease in passenger demand, the civil aviation authorities, airlines and airports try to find alternate, quick and effective measures to survive as the crisis continues worldwide [17]. While the pandemic could not be entirely stopped, air travel partly returned to service, and passengers could use airline services during the summer of 2020. It was conditional on strict hygiene and health measures being followed, not only onboard the aircraft but also at the airports. It was essential to realize that stopping the disease worldwide can be ensured by appropriate measures already at the airport. There is a high concentration of passengers and, at the same time, if an infected case boards the aircraft, measures are often unnecessary. Passengers are exposed to a much higher risk of infection. Nevertheless, most research concentrates directly on the flight and transmission of the virus onboard the aircraft or the overall impact caused by the pandemic, with little mention of the spread of the virus at airports or the adoption of measures. There are various national and international strategies or recommendations that allow and help adapt to the situation. However, the truth is that they differ significantly, and what applies at one airport may not be of use at an airport in a neighboring state. It is precisely this fact that may raise the question of how safe individual airports are. Public health measures aim to prevent the person-to-person spread of disease by separating people to interrupt transmission. The used tools are isolation and quarantine, social distancing and community containment. All these tools are being applied at an unprecedentedly large scale [18,19]. Preventive measures are the primary approach to limit the spread of cases. Still, unless these measures are already taken at the airport, there is a high probability that an infected passenger will board the aircraft. The most fundamental strategy is to wear face masks, constantly wash hands, use compact hand sanitizer and avoid touching the face and mouth after interacting with a probably contaminated environment. Although the first wave of the COVID-19 pandemic proceeded more slowly, the second wave appeared much more aggressive, with many more cases [20]. A relaxation of lockdowns and the public’s loosening of precautionary behaviors during summer 2020 has seen recorded cases and deaths rise across Europe [21]. As the second wave emerged in the rapidly spreading disease and many infected people, there is an essential requirement for efficient infection prevention and control measures. Even though the second (August–September 2020) and third waves (November 2020–present) began with growing social activity with Sustainability 2021, 13, 8499 3 of 14 lower social distancing, the spread was decreased successfully by the rapid strengthening of social distancing policies through the initial stages. Despite considerable numbers of studies [22–24] there is still only limited evidence assessing anti-pandemic measures for air travel or everyday life. 2. Theoretical Background Airports had to adjust to the new requirements and measures arising from the adopted situation. It entered into force in the May 2020 Doc 10144 ICAO Handbook for Civil Avia- tion Authorities (CAAs) on the Management of Aviation Safety Risks related to COVID-19, the ICAO’s response to the pandemic to prevent the spread of the virus and ensure the safe operation of air traffic. The ICAO developed the content with the support of aviation safety management experts. Addressing a pandemic situation requires cooperation and commu- nication at international, national and regional levels.
